Roommate: Russian teen set off mini-bombs in Pa.

ALTOONA, Pa. (AP) — The roommate of a Penn State student from Russia charged with building a suspected bomb in his bedroom says the 19-year-old recently set off three “mini-bombs” just outside their apartment.

Andrew Leff tells the Altoona Mirror that he warned Vladislav Miftakhov to get rid of the bomb-making materials. He called Miftakhov “dumb” and “crazy,” but not dangerous.

Miftakhov was in jail Sunday in Altoona after being arrested Friday and charged with possessing a weapon of mass destruction, risking a catastrophe and other counts.

Court records don’t list a lawyer for Miftakhov.

Police say they were investigating a reported marijuana growing operation at Miftakhov’s apartment when they found and dismantled the suspected bomb. They also allegedly found a suitcase containing explosives-related material.
